Brown crystal soap. Works on both metal and plastic. It's cheap. It doesn't smell. It's non toxic (although I use plastic gloves as it it can be a bit rough on the skin with continued use).It takes a bit longer to work, though. Normally, I leave the figures for a minimum of 48 hours.

I use to be a dettol man but recently tried Clean Spirit (water based white spirit) and I have to say I much prefer it. Smells less, less yukie gunk,strips better and leaves no residue. I have only one minature it’s not stripped well, a plastic marine received in a job lot. Tried everything on it but it just won’t strip. It’s like it was painted in superglue!!

Tried the Wilco paint stripper as recommended on here. Smells and looks the same as Biostrip 20 but cheap as chips, £3 a bottle. Works just as good on metal and plastic! Very happy about that there saving money thing. Thanks
